Title: Printing band
Inventor: TAGUSARI KOUJI
IPC: B41J1/20
Filed: 1979-12-19
Abstract: PURPOSE: To improve the printing quality by a method wherein in a printing band which is formed with types raised on the surface of a band like base, a junction part between a type and the base is formed into different shapes according to the kind of a type.  
     CONSTITUTION: In a printing band (a symbol 3 is a timing mark indicating a type position) which is composed of a base 1 and a type 2 (2a, 2b) raised on the surface 1a of the base, the junction part between the type 2 and the base surface 1a is made into a small arc radius R shape for a type 2a having a large area (example: [2], [0], etc.) and it is made into a large arc radius R' shape for a type 2b (example: [,], [1], etc.). With the constitution as abovementioned, a smudging is made small by increasing a deformation strength to a platen side during a hammer striking for the type having a small area, thus, a printing is performed retaining a balanced smudging quantity as a whole in accordance with the differece sizes of types.

Title: Compression bonding type semiconductor device
Inventor: IWASAKI MASAMI
IPC: H01L21/58
Filed: 1982-09-22
Abstract: PURPOSE:To discriminate the surface and back of a thermal buffer electrode member easily, and to simplify assembly by previously making the shape of the member incongruous in the surface and the back when the member is set up between the electrode of a semiconductor element and an electrode body for out the electrode. CONSTITUTION:In a transistor for power, the emitter electrodes 1e and the base electrodes 1b, height thereof differs, are surrounded by an insulating layer 2 and projected. The electrodes 1e are projected to sections higher than the electrodes 1b, and the electrodes 1e are connected to the emitter electrode body 4E through the thermal buffer electrode member 3. In the constitution, the thermal buffer electrode plate 3 is prepared by a blanking die for molding, but burr is often generated at that time. When the burr is formed downward and is in contact with the electrode 1b, an unforeseen accident is generated. Accordingly, a notch section 33b is formed previously while being put aside to a pawl section 33a on the punching side of a press, and the shapes of the surface and the back on viewing from the punched side by the press are made incongruous, thus preventing defective mounting.

Title: Tracking control system
Inventor: TAKEUCHI MOTOHIKO
IPC: G11B5/588
Filed: 1982-09-21
Abstract: PURPOSE:To perform stable tracking control with no mixture of noises, by synthesizing a track error signal with four types of pilot signals having the prescribed frequency relation of circulating record to each track and reference signals of different array orders. CONSTITUTION:The pilot signals of frequencies f1-f4 are recorded circularly on each track of a VTR tape 1, and these frequencies are selected so as to obtain frequency difference absolute values M, 3M, M, etc. for the pilot signals of adjacent tracks. A difference frequency signal between the frequencies of the pilot signals of right and left adjacent tracks is detected when the tape 1 is reproduced. This signal is mixed with reference signals which are given from an oscillator and circulate with frequencies f3, f2, f1 and f4 with which odd place tracks are replaced. These mixed signals are processed by a BPF, etc. to produce right and left error signals M and 3M. Then these signals M and 3M are synthesized to obtain a tracking error signal which is free from the effect of noises, etc. Thus stable tracking control is possible to realize a tracking control system which can easily control the manual tracking position.

Abstract: PURPOSE:To reduce element area by forming a guard ring by self-alignment method. CONSTITUTION:A high melting point metal 23 selected from Mo, W, Ta etc. is deposited at the anode, cathode electrode forming part of a Schottky diode. Then, it is placed in a heat treatment under nitrogen ambient in order to form a metal cylicide 15. This cylicide 15 is then placed again in the heat treatment under oxidation ambient in order to form an oxide film 16. Unreacted metal 23 on the oxide film 14 is selectively etched. Thereafter, the cylicide 15 is side- etched with this oxide film used as a mask and thereby periphery of electrode is exposed. Here, an impurity in a conductivity type reverse to that of the Si epitaxial layer 13 is introdued by diffusion or ion implantation method into such exposed area. A guard ring 20 is thus formed. According to this method, the Schottky diode having the guard ring can be manufactured easily without enlargement of the element area.

Title: Photographing information display device
Inventor: TAKAHASHI NAOKI
IPC: G03B17/18
Filed: 1987-06-30
Abstract: PURPOSE:To remove flickering in a displaying state by simultaneously making both displaying element in accordance with a focal distance and elements which are in front and in the rear of the said element among plural displaying elements in displaying states. CONSTITUTION:A microcomputer 21 transmits an encoding signal showing the focal distance in accordance with the set zooming state of a zoom operational ring 1 to a 1st memory so as to selectively light an LED. At the same time, the LEDs in front and in the rear of the said LED are lighted so as to display the set focal distance on a display unit 13. The encoding signal showing an irradiation angle state from a pattern 15 is inputted in a 2nd memory. The computer 21 compares the contents of the 1st and the 2nd memories and when they do not coincide, it makes a motor 11 nomrally rotate or invertedly rotate. And when they coincide each other, it stops the motor 11. Since the LED which shows the set focal distance and the LEDs in front and in the rear of the said LED are lighted in the display unit 13, the flickering does not appear and smooth display is executed even if the set zooming state finely alteres.
